SNAP-FASTENER.

Specification of Letters Patent.

Patented Oct. 3, 1916.

Application filed. January 3, 1916. Serial No. 69,964.

To all whom it may concern:

Be it known that I, ALEXANDER NATHAN, a citizen of the United States, residing at New York, in the county and State of'New York, have invented certain new and useful Improvements in Snap-Fasteners, of

which the following is a full, clear, and exact specification.

This invention relates to snap fasteners, and has for its object to produce a device of this kind which is very simple in construction and inexpensive to manufacture.

- A special object is to form the socket member of the fastener of a single piece of 1 sheet metal the design or shape of which will permit a maximum number of such members to be cut from a sheet of metal of the usual dimensions.

Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute a part of I. this specification, and then more specifically defined in the claims at the end of the description.

similar reference characters are used to des-- ignate corresponding parts throughout the several views: Figure 1 is a plan view of the socket member of the fastener, as it appears when first cut from a sheet of metal. Fig, 2 is a section taken generally on the line IIII of Fig. 1 but showing the arms or oppositely extending portions, and the rim of the circular middle portion bent into completed form. Fig. 3 is an under plan view of the completed socket member. Fig.

I is a sectional view of the socket member and button or head-carrying member assembled or engaged with one another, and Fig. 5 is a sectional view, similar to Fig. 3, of a modified form of socket member which is curved or convexed to bring the ends of the resilient locking tongues in the, plane of the periphery of said member.

The socket member is made of a single piece of sheet metal having a central portion 1 preferably circular inform, and oppositely extending portions 2 of reduced width and preferably of the same length. The socket member isformed from the piece of flat sheet metal illustrated in Fig.

1 by having the projecting portions 2 bent 555 inward upon the central portion 1 to agpoint approximately in line with the margin of In the accompanying drawings, wherein.

the central or a central opening 4 in the middle part1. From this point the extremities of the extensions 2 are bent obliquely in opposite directions to form the converging resilient looking tongues 5. The rim of the middle portion 1 is turned inward to form a flange or bead 3 extending between the folded extensions 2 for reinforcing the socket memberagainst bending stresses.

The supplemental member of the fastener consists of a flat disk 6, Fig. 4,-having a central projection 7 having a rounded and enlarged head 8 adapted. to be forced through the locking prongs 5 of the socket member after having been introduced through the central opening 4 therein. It

will be understood that the socket member is designed to be attached to one portion of a garment and the head carrying member secured to another part in any suitable man ner, so that when. the ball 8 is interlocked with the tongues 5 as illustrated in Fig. 4, the two parts of the garment will be detachably fastened together thereby, the diameter of the ball being greater than the normal distance between the tongues 5.

If desired, the socket member may be curved or rounded as shown in Fig. 5, so as to bring the extremities 50 of the locking tongues in the plane of the periphery of body portion 10. The socket member may then be arranged entirely on one face of the goods, without the locking tongues projecting into or through the material, as would be the case when said socket member is made as illustrated in Fig. 2. In the modified form, the extensions 20 are folded flat upon the middle portion 10, as

in Fig. 2, and the locking tongues are arranged in the same relative position to the central opening 40 as already described.

Having thus described my invention, what Iclaim as new and desire to secure by ters Patent of the United States is:

1. In a snap fastener, a socket member made of a single piece of sheet metal having an opening in its central portion and opposite extensions folded fiat upon the inner face of the central portion, the extremities of said extensions being bent to form straight converging tongues lying wholly at the inner side of said central portion and extending from points adjacent the margin of the opening on the inner face of said central portion to points well removed from the plane of said opening.

Let- I 2. In a snap fastener, a socket member margin of the opening on the inner face of 10 made of a single piece of sheet metal havsaid central portion to points Well removed ing an opening in its central portion and from the plane of said opening, said memopposite extensions folded flat upon the her being curved to bring its periphery inner face of the central portion, the eX- Within the plane of the extremities of said I tremities of said extensions being bent to tongues. 15
